METHOD OF MANUFACTURING TUBES, CONTAINERS, CUPS, AND THE LIKE Application filed April 23,

This invention relates to tubes, containers, lps and the like and a method for their anufacture.

The invention has for an object the prosion of a device of the class mentioned hich is of simple durable construction, deandable in use and eflicient in action, and hich can be manufactured and sold at a asonable cost.

The invention proposes a method for the anufacture of the above mentioned article hich includes the attaching of a plurality F sheet layers to each other with glue, ceent or the like in superimposed conditions id in tubular or the like formation, and 'rangin the layers prior to the attaching a that t e edges of each layer are in edge 'ntacting condition, and the seams of one int being out of the vicinity of the seams F the other joint or joints. The invention also proposes steps for the :taining of perfect edge contacting relation 3 the edges of the layers. The invention also proposes a tube, coniner, cu or the like consisting of a plulity of s ieet layers attached together with terposed glue, cement or the like, and in lperimposed relations and in tubular or .e like formation, the side edges of each yer being in edge contacting relations, and Le seams of all of the layers formed by said lntacting edges being in individually difrent vicinities to each other. I

For further comprehension of the invenon, and of the objects and advantages lereof, reference will be had to the follow g description and accompanying drawings, id to the appended claims in which the LIlO'US novel features of the invention are ore particularly set forth. In the accompanying drawings forming a aterial part of this disclosure Fig. 1 is a perspective developed view of .e layers used in this invention.

Fig. 2 is a plan view of a tube constructed :cording to this invention.

Fig. 3 is a perspective view of Fig). 2. Fig. 4 is a view similar to Fig. 3, ut illusating a frusto-conical tube.

1930. Serial No. 446,487.

Fig. 5 is a view similar toFig. 2, but illustrating another modification.

Figs. 6 and 7 are plan views similar to Fig. 2, but'illustrating further embodiments of the invention. 5

Fig. 8 is a fragmentary view of a form and sheet layer engaged therein for illustrating the method of treating the edges of the sheet ayer.

Fig. 9 is a view similar to Fig. 8, but showing two layers engaged in the form.

The tube shown in Figs. 2 and 3 consists of a plurality of sheet layers 10 and 11 attached together with interposed glue, cement or the like, and in superimposed relations and in tubular formation, the side edges 12 of each layer being in edge contactin relations, and the seams of all the layers ormed by said contacting edges being in individually different (vicinities to each other. As 7 shown on the drawings, these seams are directly opposite each other. 7

In Fig. 1 the numeral 10 indicates a developed view of the inner sheet used in Fig.

2, numeral 11 a developed View of the outer sheet. Particular attention is called that the sheet 10 is slightly shorter than the sheet 11 so that it may fit within the sheet '11 when the tube is formed. The heights of the two sheets may be "equal or slightly different if so this is desirable. The tube shown in Figs. 2 and 3 is of cylindrical form.

In Fig. 4, a frusto-conical tube 13 has been illustrated which differs only from the tube shown in Fig. 3 in that its sides are at a slope. It is made from two layers of material indicated by reference numerals 10 and 11 and the edges of these layers are in edge contacting relation with each other,

while the seams are arranged diametrically opposite each other. The layers are secured together by gluing, cementing or the like.

In Fig. 5, another modified form of the device has been shown which is very similar to the form shown in Fig. 2, but distinsimilar to the drawings, formed on one of the straight sides.

In Fig. 7, another embodiment has been shown in which the invention is applied toa pentagonal tube 16. This tube is formed from a plurality of layers, namely. an outer layer 11 and an inner layer 10 These layers have their edges in edge contacting relations with each other and. the seams formed by the edges are substantially diagonally opposite each other.

In Figs. 8 and 9, a form 17 has been shown for the accomplishing of various steps for obtaining perfect edge contacting relations of the edges of the layers of the varioustubes. The form 17 as shown on the drawings, is merely that of a cylinder. The outer layer 11 of anarticle as previously described is engaged within the form and is of such length that it snugly fits flush against the interior" face of the form with the ends 18 when in edge contacting relations slightly projecting inwards. This leaves an open space 19 between the in-bulged ends and the material of the form 17 The above constitutes the first step in the formation of the article. The next step consists in clamping the edges 18 tightly against the form 17. 'This is indicated by dot and dash lines 20 and dot and dash lines 21. The dot and dash lines 20 representrods clamped positioned on the outer side of the form and on the inner side of the layer 11. The dot and dash lines 21 indicate other. rods arranged on the outer side of the form 17 and on the inner side of the layer 11. These rods must be tightly clamped in place so that when in-bulging ends 18 are pressed against the. form, as hereinafter stated, the material of the layer cannot slip past the rods. Next an implement, indicated by dot and dash lines 22, is forced against the in-bulged edges 18 and firmly flattens them out against H the form. During thisflattening operation the fibers of the edges slightly disintegrate and engage each other so that'they are locked closed. This is very important in that when the next'step is taken, the gluing step, the glue will not readily sipe thru the seam.

After the bulge of the edges 18 has been flattened out the rods 20 and 21 are removed and glue, cement or other materialapplied upon the inside of the layer 11 without its removal from the form 17. Next the inner layer 10 is engaged within the outer layer 11 and is of such length that when the cd es 23 are in edge contacting relations, they bu ge slightly inwards from the outer layer 11. Next the clamping rods 20 and 21 are again applied in a fashion very similar tothe one previously described and the implement 22 engaged between therods' forforcing the bulged edges flat against the outer layer so that the fibers of the edges slightly disintes grate and engage each other.

Tubes, container, cups and the like constructed according to this invention are very strong and in addition are impervious to water fora long period of time. Since the seams of the different layers are not in the same 'vicinities and if water tends to gradually dissolve the glue or cement, it will take a long time before leaking occurs, since the waterwill have to travel along quite a long path. In addition, the treating of the contacting edges of the various layers as .called for produces a joint together with the cement or glue, which does not disintegrate very rapidly.

While I have shown and described the preferred embodiment of my invention,it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what Iclaim as new, and desire to secure by United States Letters Patent is 1. A method for the manufacture of tubes,

. containers, cups and the like,consisting of attaching a plurality of sheet layers to each other with glue, cement or the like, in superimposed conditions and in tubular or the like formation, and arranging layers prior to the attaching so that the edges of each layer are in edge contacting condition, the seams of one joint being out of the vicinity of the seams of the other joint or joints, and steps for obtaining perfect edge contacting relations of the edges of the layer including placii'ig the edges in edge contacting bulged relation, and then forcing the bulged portions straight so that the fibers thereof interlock- 2.
